Meloetta and the Undersea Temple! (Japanese: メロエッタと海底の神殿！Meloetta and the Undersea Temple!) is the 96th episode of the Best Wishes series, and the 753rd episode of the Pokémon anime. It aired in Japan on September 27, 2012, in the UK on December 31, 2012 and in the United States on January 19, 2013.

The spiraling staircase in the Abyssal Ruins resemble the same stairs seen in the ruins shown in the previews for the two unairedepisodes. Also, the way the Reveal Glass rises from the top of the stairs resembles the way the Meteonite revealed itself in the same preview.

This episode marks the first time that Ash has a battle directly against the leader of a villainous team.

This marks one of the very few times in the Pokémon anime when a character has threatened to kill another character, as Giovanni threatens to squash Ash and Pikachu inside of a shrinking force field cube if Meloetta doesn't give itself up.
